In the world’s era of global warming, organizations are under intensive pressure to reduce industrial waste, minimize carbon emissions, and general demand for more responsible work practices to manage a suitable environ-ment. Therefore, the study aims to examine the connection between GHRM, green capital, and environmental per-formance and moderate the role of a pro-environmental attitude. The population of this study is based on the phar-maceutical manufacturing sector in Pakistan. It includes top and middle management (i.e., CEOs, Directors, General Managers, HR, Operations, Logistics, and Supply Chain Managers of pharmaceutical manufacturing firms). The sam-ple selection assumes that they are aware of the practices and know the subject matter of the study. Therefore, the clus-ter random sampling technique was used for sample selection. In total, 525 questionnaires were distributed and 347 were the final unit of analysis for this study. The results reveal that GHRM and green capital positively and significantly affect GSCM and environmental performance. Moreover, it was revealed that the pro-environmental attitude moder-ates the relationship between GHRM, green capital, and environmental performance. So, this study contributes to the available literature on GHRM, green capital, and environmental performance. This study provides policymakers and managers with guidelines to pay attention to environmental performance. Hence, the findings support direct and indi-rect hypotheses with various theoretical and managerial implications for management and policymakers to ensure the contributing factors of environmental performance.
